IMPROVEMENT IN FRUIT-GRINDERS.

Specification forming part of Letters Patent No. 188,059, dated March 6,1877; application filed January 22, 1877.

cave grinding-faces abutting against eachv other, forming the concavityO 0, and, with the driving-drum D D, the teeth or cogs a a, the hoppere, and feed-channel b, as shown in the vertical side section, Figure 1,of the accompanying drawing.

The shaft E E, to which the grinder A is permanently fixed, passesentirely through the centers of both grinders to its bearing in theframe-work F F,.and revolves within and acts as a support to the grinderB B.

While in use, the grinder B B is locked in any desired position, and thegrinder A A is kept in constant and rapid revolution by means of adriving-belt passing around the drum D D, or by other appropriatemechanmm.

The fruit or vegetable desired to be ground is fed into the hopper e,and passing thence through the feed-channel b into the concavity C 0,between the grinders A A and B B, is first broken up by the teeth orcogs a a, permanently attached to and revolving with the grinder A A,and is then more thoroughly broken up and crushed by the abuttingsurfaces of the two grinders near their circumferences. The product thenpasses down and out between the grinders into suitable reservoirsprovided for its reception.

The escape of the pulp above is prevented by the closely-fitting band d,and the closeness of contact of the two grinders is regulated bysetting-screws, or by keys or wedges acting upon the grinder B B, one ofwhich is represented by the reference-letter f in the drawing, Fig. 1.

Fig. 2 represents an end view of the grinder A A, showing itsface-shape, which is the same as that of B B, and the relative positionsof the shaft E, the teeth or cogs a a. a a a, the concave surface 0 (J,and the framework F F.

The grinders may be made of wood, stone, or metal, and the fruits andvegetables intended to be crushed or ground by this device are apples,pears, peaches, beets, potatoes, and all other garden fruits andvegetables capable of being crushed or ground.

I claim as my invention- The combination, in a fruit-grinding machine,substantially as described, of two perpeggdicular circular grinders ofconcave abutting faces with the teeth or cogs, feed'channel, hopper,shaft, band, and driving-drum, hereinabove described.
